Perennial allergic rhinitis, a type of chronic rhinitis, is a year-round problem, and is often caused by indoor allergens such as dust and animal dander, in addition to pollen that may exist at the time. Symptoms tend to occur regardless of the time of the year.
- Use a pollen mask when mowing the grass or cleaning the house.
- Install an air purifier or at least change the air filters monthly.
- Use cotton or synthetic materials in pillows and bedding.
- Eliminate house plants.
